Here are the best informational interview questions you can ask for more career assistance:

Can you refer me to other people in your profession / company / department who could be of assistance, answer further questions, or give me a different perspective?

What professional associations should I look into?

Do you know anyone who has transitioned into this profession that I could talk to about their experience?

What books / trade publications / industry journals / blogs do you recommend that I read to learn more?

May I contact you again if I have another question?

Who are the hiring managers that could use my skills and experience in this company? Who could I contact in those departments? If I wanted to talk with any of them in the future, would you be able to introduce me?
